Metallica – Rock Star Cameos on ‘The Simpsons’

The entire lineup of Metallica made a rare cameo when their cartoon tour bus broke down while driving through Springfield. In this 2006 episode, bus driver Otto drives past the band's bus while driving the kids to school and stops to say hello.

After a heartfelt interaction with Metallica, Bart Simpson hijacks the bus while the members of Metallica jump into Hans Moleman's truck, ordering Otto to "never listen to our music again!"
